NEWARK, N.J. – With his scruffy beard and flowing locks, Roy Nelson may never look the part of an elite MMA fighter, but it’s impossible to deny the man’s punching power, as Cheick Kongo quickly discovered.

The heavyweight bout was part of the main card of today’s UFC 159 event at Prudential Center in Newark, N.J. It aired on pay-per-view following prelims on FX and Facebook.

As the fight opened, Nelson pushed forward quickly into the clinch, where it looked like he wanted to work against the fence. But referee Kevin Mulhall quickly called an end to that strategy by breaking apart the fighters as they looked to establish position.

It worked out in Nelson’s favor.

As Kongo kept his back to the cage, Nelson walked forward and unleashed an overhand right hand that landed on the ear and sent Kongo to the floor. As Kongo tries to scramble up, Nelson blasted him with another right hand that sent him sprawlin to the canvas. Mulhall then stepped in to call the fight at the 2:03 mark of the opening frame.

Nelson (19-7 MMA, 6-3 UFC) is now 4-1 in his past five appearances, and all four wins have come by way of knockout. After the win, Nelson called for a chance to fight for the UFC’s heavyweight title.
